How to use the Microsoft Zune as a HDD

It looks like you only need to mess a bit with some register settings:

1. Make sure your Zune is not plugged in and your Zune software isn't running
2. open up regedit by going to the start menu and selecting "run". Type regedt32 and hit "OK"
3. Browse to HKEY_LOCAL_MACHINESystemControlSet001EnumUSB
4. Search for "PortableDeviceNameSpace". This should be contained in the Vid_####&Pid_############_-_########_-_########_-_########Device Parameters within the above ...USB The ##'s listed here will be numbers and letters specific to your Zune
5. Change the following values: * EnableLegacySupport to 1 * PortableDeviceNameSpaceExcludeFromShell to 0 * ShowInShell to 1
6. Plug in your Zune, and make sure the Zune Software starts up.
7. Hopefully at this point you can open up "My Computer" and browse your device, though it does NOT show up as a drive letter.
8. Right now I can access it both as a hard drive and sync through the Zune Software.
